All reagents were of analytical grade and used as received.
Ethacridine lactate, potassium dihydrogen phosphate, and disodium hydrogen phosphate were obtained from Merck (Darmstadt, Germany). Hydrochloride acid, sodium chloride, and ethanol were purchased from Chemical Company (Iași, Romania). Sodium hydroxide and calcium chloride were delivered by Chempur (Piekary Ślaskie, Poland). Sodium alginate (low viscosity grade) was bought from BUCHI Laboratortechnik AG (Flawil, Switzerland).
All solutions were prepared with distilled water. When required, pH was adjusted with NaOH (0.1 M) or HCl (0.1 M).
A 500 mg/L stock solution of Ethacridine lactate was prepared and set aside at 4 °C in a closed vessel. Dilutions with concentrations between 1 and 60 mg/L were then obtained; their absorbance, recorded at a wavelength of 431 nm on a UV1280 spectrophotometer (Shimadzu, Tokyo, Japan), served for the construction of a calibration curve.
All the experiments were carried out in triplicate.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
